MACHINE FOR PUNCHING NOTE-SHEETS'.

SPECIFICATION formingpart of Letters Patent No. 673,586, dated May "-r',1901. Application le. February 23, 1901. 'Serial No. 48,574. A(No modemTo all whom it may concern.-

Be it known that I, HARRY M. SALYER, a citizen of the United States, anda resident of the city of New York, borough of Bronx, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Machines for Punching Note-Sheets, of which thefollowing is a specication.

This invention relates to improvements in machines for perforatingmusic-sheets such as are used for automatically-operated musicalinstruments.

The object of my invention is to provide a new and improved machine ofthis kind which is simple in construction, rapid in operation, andreliable in action.

In the accompanying drawings, forming a part of this specification, andin which like letters 0f reference indicate like parts in all the views,Figure l is a plan view of my improved music sheet perforating machine.Fig. 2 is a front elevation of the same. Fig. 3 is a verticallongitudinal sectional view of the same on the line 3 3 of Fig. l. Fig.4 is a detail view.

The entire mechanismis mountedin a frame A, composed of two sideuprights, and in said frame a horizontal dieplate B is held, in whichare held a series of transverse rows of dies C, an opening C' extendingfrom each die down through the die-plate.

Directly above the die-plate and separated from the same only by adistance slightly greater than the thickness of the paper to be punchedis located a punch-plate D, in which a series ofvertically-recip'rocating punches E lare mounted in line with the dies,each punch being pressed upward by a helical spring E', which pressesthe head F of the punch against a transverse stop rail F', secured inthe frame A.

Vertically and centrally above each punch a cylinder G is secured, whichcontains a vertically-reciprocating piston-rod G', secured to a pistoninv the cylinder. (Shown in dotted lines.) Each cylinder G has avalve-casing H, and said valve-casings are in communication with aseries of compressed-air chambers I, connected with acompressed-air-supplypipe J.

The sheet of paper a to be perforated is drawn through the space betweenthe dieplate B and the punch-plate D by the two friction-rollers K andL, the latter being covered with rubber and the former being fixed on ashaft K', carrying a belt-pulley K2 and a sprocket-wheel M. The roller Lis mounted in a vertically-sliding frame N, which can be adjusted, bymeans of a screw N', to produce the desired pressure and friction on thepaper ct.

Each valve-casing H is connected with a vent-pipe O, which vent-pipeshave their upper ends held in a series of transverse slats O', in theupper surfaces of which the upper end openings O2 of these vent-pipesappear. The upper end of each vent-pipe is closed by a valve P, pivotedat P' and pressed upward by a spring P2, which spring also presses abeveled nose P3 on the valve into a slot R' directly above it in a slator plate R, over which slats or plates R the matrix-sheet b, of paperorsheet metal, is drawn. This matrixsheet is unwound from a roller S,passes over a guide-roller S', and after passing over the slats orplates R passes between two frictionrollers T and U, the former beingcovered with rubber and mounted in a vertically-sliding frame T2, whichcan be adjusted by means of a screw T'. The shaft of the rollerU carriesa sprocket-wheel U', over which a chain U2 passes, which also passesover the sprocket- Wheel M. The sprocket-wheel M has three times thediameter of the wheel U', so that the matrix-sheet b moves three timesas fast as the paper d. The perforations in the matrix must be largerand separated greater distances than in the punched sheet, and for thisreason the sprocket-wheel M is made larger than the sprocket-wheel U'.The matrix-sheet b is held down-ou the slats or plates R by a hingedretaining-bar V above each held in lowered position by a latch V' and'pin V2. Each retaining-bar Vis provided in its under side with alongitudinal groove W, into which the noses P3 of the valves P can passafter passing through the slots R' and the perforations in the matrix.

A shaft d, having a fiat side d', is mounted to rock over each slat orbar O' in such a manner that it extends over the valves P and slat orplate R, which retaining-bar V can be when turned so that its fiat sideis vertical IOO bears down on the valves P and holds them closed. Eachshaft d has an arm e, which several arms c are pivoted toa rod f, bymeans of which all the shafts d together can be adjusted to hold all thevalves closed or to permit them to open-when a hole in the matrixsheet barrives at any valve. The valves must be held closed while the matrix isbeing introduced and placed upon the slats or plates R.

Whenever a hole in the matrix-sheet h arrives at a valve P, the valve isthrown upward and opened by its spring P2 and the; nose P3 of the valvepasses through the hole in the matrix-sheet. The air can thus escapethrough the corresponding vent-pipe O, permitting the compressed air toforce down th-ef piston in the corresponding cylinder G,where f by thecorresponding punch E is forced through the sheet a and into its die Cbelow it. As the matrix-sheet h moves forward it` closes the valve P andthe piston-rod Gr' isl raised, to be again depressed when a hole arrivesat the corresponding valve, and so on.

The mechanism in the valve-chamber Hl may be of any approvedconstruction andy forms no part of this invention.

As the cylinder G cannot be arranged as closely together as theperforations in the sheet a are required, they have been arranged infive groups, in which the severalcylinders l are staggered or offset, sothat the punches of any four groups punch between the slots' made by thepunches of the remaining group.

Having described my invention, what I claim as new, and desire to secureas Letters?` Patent, is-

1. #In a machine for perfora'ting note-sheets, i the combination withdies and punches and means for guiding paper between them, `of cylinderand piston above each .punch,a valve-3 vchamber for each cylinder,compressed-ain chambers with which the valve-chambers are 2 connected, avent-pipe connected with each' valve-chamber, a valve for each vent-pipeand means for conducting a matrix-sheet over said valves whereby thesame are operated, substantially as herein shown and de-l` scribed.

2. In a machine for'perforati ng note-sheets, the combination with diesand punches, and

means for guiding ,paper between them, of a spring for pressing eachpunch upward, a rail against which the heads of the punches can rest, acylinder and piston above each punch, a valve chamber for each cylinder,compressed-air chambers with which the valvechambers are connected, avent-pipe for each valve-chamber7 a valve for each vent-pipe and meansfor guiding a matrix-sheet over the vent-valves whereby the same areoperated, substantially as herein shown and described.

3. In amachine for perforating note-sheets, the combination with diesand punches, and means for guiding paper between the dies and punches,of a compressed-air-operated mechanism above each punch,- a vent-pipefor each compressed-air-operated mechanism, a valve for `each vent-pipe,which valve has a nose, a plate provided with slot-s for receiving thesaid noses, means for guiding a matrix-sheet over said plate whereby thevalves are operated and .ai retaining-bar for holding the matrix-sheeton the plate, substantially l 'as herein shown and described.
